BIDDLE, OF CAMDEN, NEW JERSEY, AS SIGNORTO TURN-BITEPROCESS 00., INC., OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OFDELAWARE snon LAST Application filed August 26, 1930. 'Serial No.477,821.

This invention relates to shoe lasts, and has for an object to provide alast especially, though not exclusively, adapted for the first lastingoperation of a turned shoe construction.

A further object of the invention is to provide along the sides of alast, recesses for receiving the excess area of the quarter or upperover the lining in a turned shoe, so that the turned shoe may be madewith the quarter larger than the lining, so that the two will properlyco-act when the shoe has been turned.

It is well known, that in the present practice of making a turned shoe,it is necessary to make the lining of greater area than the quarter, forthe reason that, in the initial stages, the shoe is constructed insideout, and the lining must be of such area as to enclose the outer sheetof material. This results in a shoe giving the lining an inclination towrinkle which is difiicult to overcome.

The invention is directed to other objects and possesses other featuresof novelty and advantage, some of which, together with the foregoing,will be hereinafter more fully set forth.

In the drawings:

Figure 1 is a view of the improved last, in side elevation,

Figure 2 is a view of the last, in top plan,

Figure 3 is an inverted plan view of the last, and

Figure 4 is a sectional view, taken on line 44 of the several precedingfigures.

Like characters of reference indicate corresponding parts throughout theseveral views.

The present invention, therefore, comprises a last having upon oppositesides,

, bottom, the grooves A are relatively wide and deep, as indicated at12. Also, these grooves are set with their ma or axes at preferably aninclination to the vertical. The posterior margin of the grooves at thetop being slightly nearer the posterior side of the last than theposterior side at the bottom. At the posterior extreme, the last isprovided with a concave part 13 in place of the usual convex, orrelatively straight construction. This concavity is for the purpose ofreceiving and accommodating the counter which is ordinarily skived atits opposite edges, forming a bulge at the central part, which thus fitsinto the concavity provided.

Also, the bottom of the last is slightly convexed, as indicated at 14,and the upper part 15, is made slightly narrower or thinner thancustomary.

Of course, the shoe last, herein illustrated, may be modified in variousways without departing from the invention herein set forth andhereinafter claimed.

The last is not limited to any particular use, but one manner of usingis disclosed in the copending application for Turned shoe and method ofmaking Serial No. 477,822, filed on even date herewith.

The invention is hereby claimed as follows:

1. A shoe last having grooves formed in the sides adjacent the heelpart, and extending from top to bottom.

2. A shoe last having grooves formed in the sides adjacent the heelpart, said grooves being tapered in extent, and extending from top tobottom.

3. A shoe last having grooves formed in the sides adjacent the heel partand extending from top to bottom, said grooves being wider and deeperadjacent the sole part than at the top.

4. A shoe last having a posterior concaved throughout substantially itsentire vertical extent.

5. A shoe last having the posterior side formed as an inwardly extendingcurve with its limits substantially at the top and bottom of the last.

6. A shoe last provided with a concavity in r I trending spaced groovesupon oppositesides of such concave position, said grooves being wideradjacent the sole of the last than at the top. w

8. A shoe last having a concave posterior 7 part, approximately Verticalgrooves, spaced. upon opposite, sidesadjacent the concave;part,

' and a sole part convex upon transverse plane.

9. A shoe last having grooves formed in the opposite sidesadjacentthe-heel, said grooves extending substantially perpendicular to theplane of the heel.

10. A shoe last having grooves formed in opposite sides adjacent theheel, the major axes of which extend substantially perpenicu a to theple- -ofthe h l, s id gr ove beingwider at thebottom; than at. the top.
